ATER COOLER OR HEATER.

SPECIFICATION forming part of Letters Patent No. 725,145, dated April14, 1903.

.. Application led .Tuly 9, 1902. Serial No. 114,898. (No model.)

To all whom it may concern:

Be it known that I, JOHN HENRY ROSE, a citizen of the United States, anda resident of Shreveport, in the parish of Caddo and State of Louisiana,have made certain new and useful Improvements in Vater Coolers orHeaters, of which the following is a specification.

My invention is an improvement in devices for cooling and heating waterand the like, and relates particularly to coolers and heaters in whichthe heating or cooling medium 1 is placed within an air-tight can .andthe latter is immersed in the liquid to be heated or cooled; and theinvention consists in certain novel constructions and combinations ofparts, as will be hereinafter described and claimed.

In the drawings, Figure l is a sectional view of my invention as in usein a waterpitcher for cooling the contents thereof. Fig. 2 is asectional elevation of the water-cooler provided with my invention. Fig.3 is a detail perspective View of the can-lid having the spring-arms forholding the can in position in the vessel; and Fig. 4i shows the canlidas provided with a double clamp, the sections of which operate at aright angle to each other. V

By my invention I provide a can or holder A for ice or other cooling orheating medium and a spring connected therewith and arranged to expandwithin the pitcher B or cooler G or other receptacle in such manner asto hold the can A suspended therein, as shown in Figs. l and 2. Thespring is preferably formed with the opposite side sections or bows C,which spring outwardly, bind at C' within the vessel, and have theirends C2 arranged adjacent to each other and so they can be pressedtogether to free the bows froml engagement with the interior of thevessel when it is desired to remove or insert the can.- As shown, thecan A is provided with a lid D and the spring is connected with the saidlid, preferably to the top thereof, and has its bows C arranged toextend beyond the sides of the lid, as shown in Figs. l and 2.

above the can and cover and in convenient position to be grasped by theoperator in inserting and removing the can. This can may It will benoticed that the handle portions C2 are centrally` and securing the sameat its middle to the cap or lid D. Y

Instead of putting the icedirectly in the water or other liquid it isput inside of an airtight can, which'is then immersed in the liquid tobe cooled. In this way the ice does not come in direct contact with theliquid, will last longer, and will not injure the liquid by mixingtherewith, and by placing the ice in an air-tight can a given quantityof ice will cool double the quantity of water in a certain length oftime as compared with placing the ice directly in the water, and bymixing some salt with the ice it will d0 still better work, as statedabove.

For heating purposes, as for keeping milk warm for children, the can maybe filled with boiling water and immersed in the liquid to heat the sameas desired.

The improved devices may be made in dife ferent sizes to it differentpitchers or coolers, and the cover or lid may be lined on the inside bya disk E, of rubber, felt, cork, or other suitable material, so thatafterthe lid is screwed on a perfectly air-tight joint may be secured.

In large coolers I may provide a double spring, with the spring stripscrossed, as shown in Fig. 4 of the drawings.

By arranging the springs t0 extend at their bowed portions laterallybeyond the can they may adapt themselves within a certain range todifferent sizes of vessels, and by making the cooling-cans in dierentsizes they may be supplied to customers, so they can be used in coolersor Water-pitchers already in hand, not requiring a special vessel fortheir application.

Y Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A heating or cooling device comprising the can, the lid therefor', andthe spring secured at its middle to the lid bent between its ends toform the opposite bows projecting laterally beyond the lid and having atits ends the projecting handle portions by which the bows may becompressed in inserting and removing the device from a vessel,substantially as set forth.

JOHN HENRY ROSE.
